In a small mixing bowl, whisk together 2 tablespoons of agave syrup, the juice of one freshly squeezed lime, and 1 teaspoon of lime zest. Add a handful of finely chopped fresh mint leaves, mixing until well combined.

Slice the watermelon in half lengthwise, then cut each half into quarters and cube the flesh into 1-inch pieces.

Wash and slice 1 cup of strawberries into rounds and pit 1 cup of cherries, halving them before combining with 1 cup of raspberries.

Gently add the cubed watermelon to the large bowl with the strawberries, raspberries, and cherries.

Drizzle the dressing over the fruit mixture and gently toss to coat.

Tear a few mint leaves and sprinkle them atop the salad before serving.
